5 steps to window funding
- 1
Involve an energy efficiency expert (EEE)
BEG funding requires a registered energy efficiency expert (EEE). We coordinate the right EEE for your project.
- 2
File the application BEFORE awarding the contract
The BAFA application must be filed before you award the contract – otherwise funding is lost. Together with the EEE we ensure the correct order.
- 3
Choose eligible windows (Uw ≤ 0.95)
Only windows with a U-value of at most 0.95 W/(m²K) are eligible. We advise on suitable PVC, aluminium or wood-aluminium models.
- 4
Professional RAL-compliant installation
Professional installation also counts as an eligible cost. We fit to RAL standard – all from one source, including disposal of the old windows.
- 5
Submit proof & receive payment
After completion you submit the proof; BAFA pays out the subsidy. We provide all the documents needed for the installation.
Why window funding in Hannover is especially worthwhile
Hannover is shaped by a high share of buildings in need of renovation: Gründerzeit and period-building quarters in the List and Linden districts meet the vast post-war stock of the 1950s to 1970s. It is precisely these buildings that often still have old windows with poor U-values - this is where the energy-saving potential is greatest and the BAFA federal subsidy correspondingly attractive. The Hannover region is also considered funding-friendly and is a model region for serial renovation, which puts the renovation needs even more in focus. VL-Innovativbau takes the entire funding process off your hands: we coordinate the mandatory energy efficiency expert, ensure the right application timing (application before the contract is awarded) and install your new windows with a Uw value ≤ 0.95 professionally in line with RAL standards. This way you combine the maximum grant with permanently airtight, energy-efficient windows - subject to funding approval.

Frequently asked questions about funding
Through BAFA (BEG individual measures) you receive a 15% grant on the eligible costs, and up to 20% with an iSFP (individual renovation roadmap). One requirement is, among others, a Uw value ≤ 0.95. Eligible costs are up to €30,000 (with iSFP up to €60,000) - all subject to funding approval.
Yes. The BAFA application must be submitted before the contract is awarded, otherwise the funding is forfeited. In Hannover we pay close attention to this timing and align the application and the contract.
The iSFP (individual renovation roadmap) is a renovation strategy for your building prepared by the energy efficiency expert (EEE); it increases the grant from 15% to up to 20%. The EEE is mandatory for the funding - VL-Innovativbau coordinates it for you, but does not itself provide legal or tax advice.
